Description
Technical field
The present invention relates to the research field of orchard Pipe spraying, more particularly to a kind of medicine dress mixed online based on Pipe spraying
Put.
Background technology
During traditional spraying operation, generally using premixed mixed prescription formula.This mixed prescription formula needs elder generation when mixing medicine
Agricultural chemicals and water are poured into medicine-chest by a certain percentage by operating personnel, is manually being stirred, be sufficiently mixed agricultural chemicals and water, with
Used during for spraying.But there is many drawbacks in the mixed prescription formula：(1) operating personnel may contact during preparating liquid
To agricultural chemicals, pesticide poisoning is caused；(2) for the plunger displacement pump and medicine-chest sprayed directly and Pesticide Exposure, most agricultural chemicals sheets
Body has corrosivity again, and pump and medicine-chest must use corrosion-resistant material, cause production cost to increase：(3) mixed in medicine-chest
But the agricultural chemicals being not used causes the wasting of resources, and, liquid treatment is bad also to cause serious environmental pollution.
Premixed mixed prescription formula because of the numerous requirements that can not meet agricultural sustainable development of its drawback, and compared to premixed
Mixed prescription formula, mixed prescription formula is to separate medicine-chest and water tank online, using spraying machine pipe-line system water flow inside or spraying machine pipe
Road extra power completes the on-line mixing of agricultural chemicals and water, realizes the standardization of agricultural chemicals, specialization, applies, with environment precision

Medicine technology mixed online high, the update to agricultural plant protection machinery and facility is significant.
The agricultural chemicals that foreign countries are researched and developed at present is directly injected into the mixed medicine online such as system and the domestic jet mixing apparatus researched and developed
Device be all mainly apply in, in large-scale mobile equipment for plant protection equipment, using with certain limitation.And in mountain region really
Garden cannot carry out portable plant protection spraying operation, can only carry out spraying operation using pipeline.But due to current Pipe spraying operation
Remaining in the liquid in pipeline afterwards cannot discharge, and the practice universal at present is the injected clear water toward in pipeline, using clear water to pipeline
Cleaned, but this practice had both easily caused agricultural chemicals waste, and processing sordid agricultural chemicals can cause severe contamination to environment again.
However, the research for being currently based on the online medicament-mixing device of Pipe spraying is substantially at the stage of blank out, therefore, to reduce mountain
The waste of ground orchard Pipe spraying operation Pesticides, avoid serious environmental pollution, and in making up, large-scale equipment for plant protection equipment
The drawbacks of cannot be introduced into hillside orchard and carry out spraying operation, online medicament-mixing device and control method based on Pipe spraying are developed,
Being wasted and environmental pollution to reducing the agricultural chemicals caused in Pipe spraying operation, and improve China's mountain farming development level has weight
Want meaning.
